DETAILED DESCRIPTION OF THE INVENTION

FIGS. 1 through 14, discussed below, and the various embodiments used to describe the principles of the present disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged wireless communication system.

Hereinafter, a method and apparatus for utilizing callee information and location before call establishment will be described.

With the rapid growth of Internet access using a portable terminal, new value added applications have been created such as mobile banking, mobile offices, and the like. In particular, if these applications are applied to typical telephony functions of the portable terminal, the applications may have a broader effect and a greater influence.

The present disclosure is provided to easily acquire user information that can be helpful when performing an outgoing call to a callee by confirming a current location of the callee, whether the callee is available for the call, a schedule of the callee, personal information of the callee, etc., before a user performs an outgoing call by using a portable terminal.

For example, when the call is not available because the callee is in a business meeting or the like, the present disclosure can predict a next time at which a caller can make a call without interfering the callee by directly recognizing that the call is not available. The callee can show promotions, advertisements, or the like of the callee during the call and thus can use the present disclosure as a means for personal advertisements.

In the present disclosure, the user information is provided by a user terminal (i.e., a portable terminal) and is delivered to the callee by using a relay server.

The present disclosure can report a location of a portable terminal of a user to a callee by using a cell identifier (ID) of a Base Station (BS) or a Global Positioning System (GPS), and can store personal information (e.g., a photo, a profile, and the like) into the portable terminal and thus can configure information desired to be shown by the callee according to a user's preference. In addition, the present disclosure can report a current status of the user on the basis of schedule information previously input by an individual user by using a schedule management program.

FIG. 1 illustrates a structure of a system for providing user information according to an embodiment of the present disclosure.

Referring to FIG. 1, the system for providing user information includes an information requesting device 100, a relay server 110, and an information providing device 120. Although it is assumed herein that the information requesting device 100 and the information providing device 120 are portable terminals, any device can be used as long as it can transmit and receive information to be exchanged.

The information requesting device 100 transmits a user identifier (ID) (i.e., a phone number, a Social Network Service (SNS) ID, an e-mail, a social security number, a bank account, and the like) of the information providing device 120 and an information request message to the relay server 110 (Operation 1). Further, in order to protect and manage personal information, a user ID of the information requesting device 100 is also transmitted to the relay server 110.

The relay server 110 transmits the information request message together with the user ID of the information requesting device 100 to the information providing device 120 (Operation 2). The user ID can be pre-registered to the relay server 110.

The information providing device 120 evaluates the user ID of the information requesting device 100 to determine whether to provide user information.

If the information providing device 120 determines to provide the user information, the information providing device 120 transmits request information of the information requesting device 100 to the relay server 110 (Operation 3).

Thereafter, the information requesting device 100 receives information requested from the relay server 110 (Operation 4), and then displays the received information.

In the present disclosure, the information delivered to the information requesting device 100 is provided from the information providing device 120. Examples of the provided information include location information and user information.

The location information is information regarding a current location of the information providing device 120 by using a cell ID of a BS or a GPS. The user information is information which is stored and configured in the information providing device 120. The user information is managed by the information providing device 120. Examples of the user information include schedules, photos, setup messages, and the like.

FIG. 2 is a flowchart illustrating a process of providing location information of an information providing device according to an embodiment of the present disclosure.

Referring to FIG. 2, when the information providing device receives a location information request from an information requesting device via a relay server (Block 210), a current location is determined on the basis of GPS information of the information providing device or a cell ID of a BS (Block 220).

The information providing device transmits information regarding the determined location to the relay server (Block 230).

Thereafter, the relay server transmits the location information to the information requesting device. Upon receiving the location information, the information requesting device displays a location of the information providing device by using the location information.

If the information requesting device is a device which is allowed to provide information, the information providing device transmits the location information to the relay server.

FIG. 3 is a flowchart illustrating a process of providing schedule information of an information providing device according to an embodiment of the present disclosure.

Referring to FIG. 3, when the information providing device receives a schedule information request from an information requesting device via a relay server (Block 310), the information providing device evaluates a currently stored schedule (Block 320).

When evaluating the schedule, a user's schedule (e.g., a date, a time, a place, a content, and the like) is evaluated, and it is confirmed whether the user's schedule exists at a current time.

If the user's schedule exists at the current time (Block 330), the information providing device transmits to the relay server that call reception is currently not available (Block 340). That is, it is reported that a current status is a not-available status.

If the user's schedule does not exist at the current time (Block 330), the information providing device transmits to the relay server that call reception is currently available (Block 350).

If the information providing device reports the current status, a message including the current status can be transmitted.

Alternatively, the information providing device interworks with a schedule management system used by a user and thus can evaluate a current schedule when a schedule information request occurs and can deliver a result of the evaluation to the relay server.

Upon receiving the information request, the information providing device can transmit to the relay server a photo configured by the user among photos stored in the information providing device.

In addition, the information providing device can store personal information (e.g., a birthday, an e-mail, a home, an office, and the like) and upon receiving the information request, can transmit the personal information to the relay server so that the personal information is delivered to the information requesting device.

In addition, upon receiving the information request, the information providing device can transmit a text message, a voice message, or the like to the relay server so that the message is transmitted to the information requesting device.

If the information requesting device is a device allowed to provide information, the information providing device transmits the aforementioned information to the relay server.

FIG. 4 is a flowchart illustrating a process of filtering a target to which an information providing device provides information according to an embodiment of the present disclosure.

Referring to FIG. 4, when the information providing device receives a user ID (e.g., a phone number) of an information requesting device (Block 410), the information providing device determines whether to provide user information to the information requesting device corresponding to the user ID (Block 420). That is, whether to admit to provide the user information is determined.
